DRAFT-GVEAR FOR HARVESTERS.

Harvesters, of which the following is a speci-` fication.

This invention relates to the draft-gear for4 that class ofharvesting-machines which are drawn by a single horse or otherdraft-animal and which are used interchangeably for mowing grass and forreaping grain. When the machine is used for mowing, the draft-animalshould travel in a track which is about in line with the grainward wheelor the inner end of the linger-bar, in which track the horse injuresneither the standing grass nor the cut grass. In order to allow thehorse to travel in this track, the thills must be arranged toward thegrainward side of the machine. When the machine is used for reapinggrain, this position of the thills is not admissible, as the thillswould strike the standing grain', and itis therefore necessary to shiftthe thills to a central position in order to adapt the machine forreaping.

The object of my invention is toprovide simple, efficient, andconvenient means for.

adjusting the thills and the draft device laterally, so that they can beplaced either in the proper position for mowing or for reaping.

In the accompanying drawings, consisting of two sheets, Figure l is atop plan View of a mower, showing the thills in full lines in theposition for mowing and in dotted lines in the position for reaping.Fig. 2 is a top plan view, on an enlarged scale, of the rear portion ofthe thills and connecting parts in the position for mowing. Fig. 3 is alongitudinal sectional elevation ofthe draft device in line 3 3, Fig. 2,0n a still further enlarged scale. Fig. 4C is a vertical cross-sectionin line 4e 4, Fig. 2, on an enlarged scale. Fig. 5 is a top plan view,on an enlarged scale, of the rear portion of the thills and connectingparts in the position for reaping. Fig. 6 is a vertical cross-section inline 6 6, Fig. 5, on a still further enlarged scale.

Like letters of reference refer to like parts in the several figures.

A represents the frame of the harvester, which may be of any suitableconstruction.

B represents a short or stub pole, which is secured to the frame forsupporting the thills O.

D represents an auxiliary draft-stub, which is arranged longitudinallyon the grainward side of the pole and at a suitable distance therefrom.This draft-stub is secured to the grainward side of the pole by abracket E. The latter and the auxiliary draft-stub form a lateralextension or enlargement of the pole,

on the grainward side thereof, for supporting the thills and the draftdevice when the thills are placed in the position for mowing, as shownin full lines in Figs. l, 2, 3, and 4e. The thills consist oflongitudinal front portions f, which are preferably formed of wood, anda rear frame which is preferably constructed of iron` or steel-forinstance, angleiron or steel, as shown, although other forms ofcommercial iron or steel may be employed. This metallic rear frame ofthe thills consists of a front cross-bar g, a rear cross-bar h, whichhas its ends h curved forwardly to connect with the ends of the frontcross-bar, and connecting-shoes or socket-plates 7l, to which the endsof the frame-bars and the front portions of the thills are secured. Thetwo cross-bars of the thill-frame rest upon the pole and theY ranged inthe bolt-holes ZVZ of the frame-bars, which holes are arranged in theproper position for bolting the thill-frame to the pole and stub whenthe thills are in the position for The extra bolt-holes Z2 Z3 arepromowing.

are in the position for reaping, as shown in' Figs. 5 and 6.

The draft device shown in the drawings is constructed substantially asshown in Letters Patent No. 594,596, granted to Adriance, Platt t Co.,as assignee of myself, November 30, i897, and consists, briefly stated,of the following parts: M represents the whifietree, which is hung to aclevis m. The latter is carried by a bolt n, which depends from a slideN. This slide is mounted on a longitudinal guide-bar O, on which theslide can move backward and forward and which is provided at its frontand rear ends with upwardly-projecting arms o o', by which it isattached to the under side of the pole or of the stub, according totheposition of the thills. The slide N is provided with arearwardly-projecting rod P, to which a draft-springp is applied. rlheclevis m is connected by a link q with an auxiliary draft-rod q', whichconnects with the coupling-bar of the mower. (Not shown.)

When the thills are required to be changed from one position to theother, the bolts are released and withdrawn, therebyT disconnecting thethills from the pole and auxiliary stub and det-aching the draft device.The thills are then shifted to the desired position and secured,together with the draft device, to the pole and auxiliary stub. In thegrainward position of the thills (shown in Figs. l to 4) the draftdevice is arranged underneath the auxiliary stub and is carried by thesame. In the central position of the thills (shown in I Figs. 5 and 6)the draft device is arranged underneath the pole, near the stubblewardside thereof, and is carried by the pole.

I claim as my inventionl. In a harvester, the combination with the polehaving a lateral extension on the grainward side, of thillsprovidedatthe, rear end `with a frame which rests upon said pole and extension andis laterally adjustable thereon to permit the thills being placed intheposition for mowing or for reaping, and means whereby said thill-framecan be secured in either adjusted position, substantially as set forth.

2. In a harvester, the combination with the vpole having a lateralextension on the grainward side, of thills provided at the rear end witha frame which rests upon said pole and extension and is laterallyadjustable thereon to permit the thills being placed in the position formowing or for reaping, means whereby said thill-frame can be secured ineither adjusted position, and a draft device adapted to be secured tothe under side of the pole or its lateral extension to correspond to theposition of the thills,substantia1ly as set forth.

3. In a harvester, the combination with the pole having on the grainwardside a lateral extension composed of a longitudinal stub and aconnecting-bracket, of thills having a rear frame provided with frontand rear crossbars Which rest upon said pole and stub and
